Direct Known Subclasses:

OrderedCollectionMapping

public class CollectionMapping

extends AbstractCollectionMapping

implements LoadSecondary, StoreSecondary, SecondaryTable

Represents a collection of simple values such as Integers, Strings, etc. CollectionMappings are stored in a separate table from the primary values of the owning class. Each row of the table holds two values: a single element of the collection in the data column, and the PK value of the owning object in the ref column.

Method Detail

join

public void join(ObjectSelect sel)

Description copied from class: FieldMapping

Join this mapping to the given select statement. For basic mappings, this no-op method implementation will suffice. Secondary table mappings should override this method to do the proper join.

Overrides:

join in class FieldMapping

load

public void load(StateManagerImpl sm,
                 Object[] pks,
                 int field,
                 SQLExecutionManager sqlem)
          throws SQLException

Description copied from interface: LoadSecondary

Load the value of this mapping for the given instance. Relations to other persistent types are loaded as PersistenceCapable instances.

Specified by:

load in interface LoadSecondary

Following copied from interface: com.solarmetric.kodo.impl.jdbc.ormapping.LoadSecondary

Parameters:

stmnt - The caller is responsible for closing the statement.

select

protected void select(Select sel,
                      StateManagerImpl sm,
                      Object[] pks,
                      int field)

insert

protected void insert(Insert insert,
                      Object value,
                      int index,
                      StateManagerImpl sm,
                      Object[] pks,
                      int field)

addValueMatchCondition

protected void addValueMatchCondition(SQLStatement sql,
                                      Object value,
                                      ClassResolver resolver)

canMap

protected boolean canMap(FieldMetaData fmd,
                         ClassResolver resolver)

install

protected void install(FieldMetaData fmd,
                       JDBCConfiguration conf,
                       ClassResolver resolver,
                       DBDictionary dict)

getSecondaryTable

public Table getSecondaryTable()

Description copied from interface: SecondaryTable

Return the secondary table used by this mapping.

Specified by:
